Infant Single Ventricle Monitoring Program (ISVMP): Outpatient Pathway - Stage I Discharge to Stage II Operation

Decision guidance (discuss with surgeon if concerns), considerations include:

  1. Standard recommended time is 4.5m.
  2. Consider earlier stage II (4 months) for restrictive shunt in growing patients with otherwise straightforward anatomy
  3. Consider later stage II (5 months) for bilateral SVC particularly if patient is on smaller side.
  4. Note that interstage risk is higher in patients with BT shunt than RVPA conduit (Sano modification).
  5. For patients with interrupted IVC typical time for second stage (Kawashima) is around 6 months
